Double-Population Link-Wise Artificial Compressibility Method for Simulating Two-Dimensional Magnetoconvection

Autor: Souheil Elalimi, Sassi Ben Nasrallah, Mohamed Hamdi

Publikováno v: Mathematical Problems in Engineering, Vol 2019 (2019)

The recently developed Link-Wise Artificial Compressibility Method (LW-ACM) with double population is presented, validated, and then applied to magnetoconvective flow. The validation step evolves in two stages. First of all, we used the problem of mi
